The real problem is these kids now are throwing curves and breaking balls by the time they’re 8 years old. They play travel ball year round, by the time they finish high school they’ve already got half a career mileage on that arm. The youth leagues have inning counts for most of these kids but they’re playing 5 games a weekend almost year round PLUS practice..my nephew has been playing travel ball now for 6 years, he’s 14 now and luckily he’s got an organization and coach that know they’re kids and don’t over work them but I’ve seen TONS of teams and kids he’s played against that aren’t so lucky..
